The metallurgical area includes a variety of industries such as steel foundries, aluminum and other metal producers as well as heat treatment and inerting of metallic products or compounds. HiQ® pure gases, calibration and monitoring standards are used in areas including combustion control, environmental emission monitoring, health and safety monitoring, and furnace atmospheres. Specialty equipment cylinder regulators are used in many areas to control gas cylinder pressures while ensuring purity is not compromised.

During mining operations a variety of instrument Zero gases and calibration gas mixtures are used to calibrate gas sensors for oxygen deficiency, carbon monoxide, methane, carbon dioxide, as well as other compounds to ensure employee safety. Linde portable gas solutions make calibration and measurement tasks safer and easier.
